AD HOC ANNOUNCEMENT PURSUANT TO ART. 53 LR

Muttenz, 12 May 2025 – Clariant, a sustainability-focused specialty chemical company, today announced that on 9 May 2025, the company received a claim for damages against four companies, including Clariant, from Dow Europe with the court of Munich, Germany. The claim alleges damages totaling to around EUR 767 million in relation to infringement of competition law on the ethylene purchasing market which was sanctioned by the European Commission in July 2020.

Dow Europe was not a supplier of ethylene to Clariant and Clariant has substantiated economic evidence that the conduct of the parties did not produce any effect on the market.
